Check the advertised PHP version from a URL or hostname.

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use HTTPS for a bare hostname.

    line 12

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

SKILL.md

From this skill's directory, run:

node scripts/phpcheck.js "https://example.com" --json

Use HTTPS for a bare hostname. The checker reads Server and X-Powered-By headers. If the version is hidden, report unknown.

Versions below an upstream fix return potentially_vulnerable with exit code 1. PHP 5.4–5.6, 7.0–7.4, 8.0 and 8.1 also return this warning. A higher patch number on those branches, such as 8.1.35, does not establish a fix.

Exit code 1 is a version-based warning, not proof that the installed package is unpatched. HTTP headers cannot tell whether the version contains a backported fix. Describe the result as potentially vulnerable, never confirmed vulnerable.

An ok result with exit code 0 means only that the advertised stable version meets an upstream fixed release: 8.2.35, 8.3.36, 8.4.27 or 8.5.12. The installed build is not verified. Missing or unrecognized versions, prereleases and failed checks return unknown with exit code 3.

Headers can be changed. A server-side check of the package serving the site is stronger evidence. Do not run exploit probes.

Exit codes 1 and 3 are check results. Invalid arguments exit with code 2.

    How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.
